TALKING-CLOCK OR THE LIKE.

Specification of Letters Patent.

Patented Aug. 15, 1916.

Application filed June 26, 1914. Serial No. 847,480.

To all whom it may concern:

Be it known that'I, Max MARCUS, a subject of the King of Prussia, residing at Pankow, near Berlin, Germany, have invented new and useful Improvements inv Talking-Clocks or the like, of which the following is a specification.

This invention relates to a device for releasing the sound reproducing mechanism of talking clocks and the like.

Compared to the releasing. devices for the sound reproducing mechanism in alarm clocks and the like, hitherto known, the es sential feature of this invention consists in the fact that, owing to the arrangement of a locking device on the gear of the hands, the driving gear of the sound reproducing mechanism or the like 'is directly released and, after moving a locking lever, stopped again and automatically reset for the next release, without any further manipulation.

In the accompanying drawings, Figure 1 shows a construction of the device in side elevation. Fig. 2 is -a front elevation of Fig. 1, Fig. 3 a plan of Fig. 1, Figs. 4: to 6 are detail views of the release device shown in Figs. 1 to 3, while Figs. 7 to 9 show a somewhat modified construction in which two disks with notches are provided in place of two sleeves with notches.

On an auxiliary spindle 5 connected to the hour hand spindle a by means of intermediate wheels-with a given ratio of transmission, is mounted a sleeve 0 with a disk d secured to it and provided with divisions corresponding to the time intervals; the disk can be set to release the mechanism at any predetermined moment by a division on the -disk being brought opposite a hand secured to the intermediate spindleb.

A sleeve f provided with a cam groove 6 is secured to the sleeve 0 while a, second sleeve 9, also provided with a cam groove and projecting into the former, is rotatably mounted on the sleeve 0, in such a manner that, owing to the action of a torsion spring c, it always has the tendency to cover the notch c in the sleeve 7. A locking lever m engaging by means of a projectionk with the circumferential periphery of the two sleeves f 9 under the action of a tension spring Z,-keeps the spindle n, which has driving connections with the spring motor 0 in the position of rest by means of a stop 9 or its equivalent until the notch e in the sleeve f has rotated to the extent determined for it by the disk (Z. The locking lever m, after it has pressed back the sleeve 9 by means of the cam surface it, thus simultaneously tensioning the spring z, suddenly springs into the notch e, of the sleeve f andin that way releases the spindle 11, together with its train of wheels, governor, etc., operated by the spring motor 0, and controlled by the stop 9. By simply moving back the locking lever m (which is done by hand in the present embodiment) the further movement .of the driving spindle of the talking machine is stopped, the locking lever on at once engaging with the stop 9 of the driving spindle. If the lever m is moved back by hand after its engagement with the notch e of the sleeve f the inner sleeve 9 springs back into place covering the notch and the lever m thus rests upon the front or circular edge'of the sleeve 9 over which it slides while the sleeves continue their rotation. But if the lever m is not moved back by hand it remains in the notch until the sloping edge thereof gradually returns it to the level of the front edge of the sleeve in which position it stops the rotation of the driving spindle n.

The sleeve f is heldflin driving connection with the auxiliary spindle b and through it with the hour hand spindlea by a spring 1' which presses thesleeve or the face of the disk a! mounted upon it, into frictional engagement with the back of the hand or pointer fastened on to the spindle b. The

sleeve thus normally rotates with the spindle b-but can be turned relatively thereto for setting purposes. After .the driving spindle n of the sound-reproducing mechanism has been stopped by the locking lever being moved back the next temporary release will occur after a time interval corresponding to the rate of transmission of the wheels. The

winding is accomplished by means of a spindle s and the gear 0 is designed in accordance with the speed required for the driving spindle a. When the disk 03 has been set for a given time, it is therefore not necessary,

lease at a given time interval corresponding to the rate of transmission of the wheels, except to bringthe locking lever m back to the original position, after the release has taken place.

If the time of release is to be altered, this may be ,done simply by shifting the disk (Z to the desired time opposite the hand of the intermediate spindle b, the projection is of the locking lever m then springing. into the notches of the sleeves f 9 after a correspondingly longer or shorter time interval.

To enable anydesired adjustment to be eflected, even without having to consider the position of the hand on the dial, the disk cZ withthe divisions can *be provided in the known manner with a line t which can be setagainst a fiXed index finger u, for instance so that when the two marks coincide, the release of spindle n always takes place.

Figs. 7 to 9 show a modified construction for the same purpose, in which, in place of the two sleeves f and 9 provided with notches, two disks 7 and g are employed, the application and the working remaining the same as in the arrangement already described.

lVhat I do claim as m invention, and desire to secure by Letters Patent of the United States, is
